Those languages have the same semantics as Erlang in many important respects. For example, there are no mutable variables in any of those languages. They all have the same concurrency model, the same memory management etc.

  it does. values are immutable in the BEAM, not at language level. The impact of bugs is minimized by compartmentalization. This is done from the lowest level where each data structure is separate and immutable [1] But you can simulate mutability with stateful processes.
